Anaphylactic101 Posted February 14, 2022 Share Posted February 14, 2022 2018 Mack LC613 (Trash truck) As the title shows I have a P2436 code for DPF Soot Accumulation it stays active anytime the key is on. I previously had a code for the 7th injector solenoid that caused issues driver waited until truck was in derate to bring it in. Replaced the AHI module for a stuck open solenoid. After replacing the module I performed a regen and this P2436 came up. I have looked unto the TSBs relayed and replaced 7th injector to be sure that wasn't an additional issue. Performed DPF Soot Accumulation reset but the Soot level will not come off of 140% All numbers during Regen are within Spec and the DPF differential sensor says 0.1psi. Any help would be greatly appreciated. Can provide additional info as required as I am sure I'm missing something. Quote Link to comment Share on other sites More sharing options...
